Attunity CDC Modernization Guide

Attunity CDC captures changes made to data in one location and replicates those changes to another location, ensuring data consistency across systems. It monitors database logs to identify and apply these changes.

Attunity CDC is a middleware solution. It facilitates the movement and synchronization of data between different systems, acting as an intermediary between data sources and targets.

Organizations that require real-time or near real-time data replication between systems, particularly those using mainframe databases like DB2, Adabas, IMS, and VSAM, benefit from Attunity CDC.

A company should consider using Attunity CDC when they need to maintain synchronized copies of data across different systems, ensure data availability for reporting or analytics, or migrate data with minimal downtime.

Alternatives to Attunity CDC include IBM Data Replication, SQData, and Rocket Data Replicate and Sync. These products offer similar data replication and synchronization capabilities.

Attunity CDC requires access to the source database logs to capture data changes. It also needs a network connection between the source and target systems to transmit the replicated data.

Attunity CDC runs on z/OS and typically operates within an LPAR. It is dependent on z/OS and requires access to specific subsystems to monitor and capture data changes from databases like DB2, Adabas, IMS, and VSAM.

Attunity CDC primarily supports databases like DB2, Adabas, IMS, and VSAM as data sources. It captures changes from these databases by monitoring their transaction logs.

Attunity CDC uses a log-based change data capture mechanism. It reads the database transaction logs to identify inserts, updates, and deletes, and then applies these changes to the target database.

Attunity CDC ensures data consistency across systems, which is crucial for accurate reporting, analytics, and decision-making. It minimizes downtime during data migration projects, reducing business disruption.

By providing real-time data replication, Attunity CDC enables organizations to make timely decisions based on the most current information. It reduces the risk of data loss or corruption during data migration.

Attunity CDC can reduce operational costs by automating data replication processes and minimizing the need for manual data synchronization efforts. It also improves data governance by ensuring data consistency across systems.

Attunity CDC supports various authentication methods to secure access to the system and the replicated data. The specific methods supported depend on the configuration and the underlying systems.

Attunity CDC uses an access control model to manage user permissions and restrict access to sensitive data. The specific model used depends on the configuration and the underlying systems.

Attunity CDC encrypts data both in transit and at rest to protect it from unauthorized access. The specific encryption algorithms used depend on the configuration and the underlying systems.

Attunity CDC provides audit logging capabilities to track user activity and data changes. These logs can be used to monitor security events and investigate potential security breaches.

Implementing Attunity CDC requires technical expertise in data replication, database administration, and network configuration. Ongoing operational requirements include monitoring replication processes, managing user access, and troubleshooting issues.

Common implementation challenges include network connectivity issues, database compatibility problems, and performance bottlenecks. Proper planning and testing are essential for a successful implementation.

Attunity CDC provides administrative interfaces for configuring replication processes, managing user access, and monitoring system performance. These interfaces may include command-line tools, graphical user interfaces, or web-based consoles.

Monitoring and logging capabilities in Attunity CDC allow administrators to track data replication processes, identify potential issues, and ensure data consistency. These capabilities are essential for maintaining a reliable data replication environment.
